Abstract
Description
- The present invention relates to a medical puncturing device e.g. for use in connection with the insertion of a soft cannula where the soft cannula e.g. forms part of a infusion device for subcutaneous delivery of a medication or a therapeutic fluid by means of an external infusion system and more particularly to a medical puncturing device capable of being discarded without the danger of causing unintended harmful injuries to persons afterwards.
- The medical puncturing device will in the following be explained in connection with the field of subcutaneous infusion devices. Such infusion devices are generally known in the art for delivering a medication or a therapeutic fluid to a subcutaneous site in a patient. Such devices commonly comprise a soft tubular cannula extending from a housing adapted to receive the desired medication via means, e.g. disconnectable means, for suitable connection to further components of the infusion system. The possibility of disconnecting the infusion set from the further parts of the infusion system is provided in order to improve the user comfort. In order to place the soft cannula at a subcutaneous delivery site, a medical puncturing device comprising a rigid needle and a handle is used. The rigid needle is inserted through the hollow soft cannula and extends beyond the outer tip of this. The soft cannula is inserted into the subcutaneous fat layer of the patient together with the rigid needle, which is afterwards withdrawn leaving the soft cannula at the infusion site. In order to provide such disconnectable medical puncturing device and still maintain a fluid-tight sealing towards the interior of the housing and the tubular cannula that prevents contamination of the infusion site, such devices are commonly provided with a self-sealing penetrable septum on the housing. Upon withdrawal of the needle from the septum this provides a fluid-tight sealing towards the interior of the housing. The septum and the needle further provides a fluid-tight sealing between the housing and the connector means when medication or therapeutic fluid is delivered to the patient from the external infusion system. Subcutaneous infusion devices of this generally known type are known from e.g. U.S. Pat. No. 5,522,803 to Teissen-Simony and U.S. Pat. No. 5,545,143 to Fischell.
- The use of a medical puncturing device comprising a rigid needle may lead to some disadvantages during use of such device, viz. the potential danger of unintended exposure to the needle tip after the needle has-been discarded.
- A medical puncturing device of a type providing some remedy for these disadvantages is disclosed in U.S. Pat. No. 5,533,974. This previously known device comprises a rigid needle and a protector housing wherein a biasing element, a cam and a gripping element are provided in order to lock the protector housing in relation to the needle at the pointed tip of this.
- A further device is disclosed in U.S. Pat. No. 5,279,591. This previously known device comprises a rigid needle and a protector housing wherein a resilient spring means is provided to block the needle tip upon sliding the protector housing to the needle tip.
- A still further device is disclosed in WO 9305840. This previously known device comprises a rigid needle and a protector housing wherein a resilient guard element is provided to block the pointed needle tip upon sliding the protector housing to the needle tip. Means for limiting the sliding movement are provided hereby ensuring the position of the protector housing.
- Although these previously known medical puncturing devices to some extent give a satisfactory result with respect to the prevention of unintended and harmful needle sticks they all have a complicated construction requiring a cumbersome assembling process.
- For this reason there is a need for improvements in the field of medical puncturing devices, the improvements relating to providing a medical puncturing device having satisfactory properties particularly with respect to providing a medical puncturing device which can be dismantled and discarded without the risk of causing any injuries, and at the same time being of a simpler construction requiring less effort in the manufacturing process.
- The infusion needle according to the invention remedies the above mentioned disadvantages and provides further advantages which will become apparent from the following description.
- In order to provide remedy for the above mentioned disadvantages a medical puncturing device has been developed, said medical puncturing device comprising a rigid needle being at one end adapted for facilitating the puncturing and comprising at the opposite end a hub, the hub comprising a handle part and a shield part being pivotable in relation to the handle part and further comprising locking means on the shield part and the handle part, the locking means being adapted to interlock the shield and the handle part in a pivoted position of the shield part where the rigid needle is covered by this.
- By these features a simple construction is obtained which provides a reliable function as to preventing the risk of causing any injuries upon dismantling and discarding of the device.
- In a preferred embodiment the shield part comprises a recess for accommodating the rigid needle. This can conveniently be obtained by configuring the shield part with an essentially U-shaped cross section.
- The locking means on the handle part preferably comprises two arms having on their opposed sides barbs adapted to interlock with the corresponding locking means of the shield part. The locking means on the shield part preferably comprises two side flanges adapted to interlock with the corresponding locking means of the handle part. The flanges or the barbs are preferably tapered to facilitate the insertion of these into the corresponding locking means of the handle part and the shield part, respectively.
- In order to facilitate the handling, the shield part preferably comprises an operating handle.
- The hub is conveniently configured as a single part where the transition area between the handle part and the shield part is an area with a reduced rigidity, e.g. an area with a reduced material thickness. The medical puncturing device according to the invention is preferably manufactured from a plastics material, e.g. by a moulding process.
- In a convenient embodiment the hub is prior to pivoting of the shield part adapted to grip around a body, e.g. an infusion device where a soft cannula belonging to this is to be inserted into a human body.

The needle hub comprises ahandle part 3, which is at one side connected to ashield part 4 via ahinge 5 formed as a material area with a reduced thickness. Theshield part 4 has the shape of ahalf tube 6 having at the edges at both sides flanges 7,8. Theshield part 4 comprises apivoting handle 17. At the opposite side of theneedle hub 2 in relation to the needle connection point theneedle hub 2 comprises twoarms barbs opposed sides - From
FIG. 2 the puncturing device appears in a side view more clearly showing thetransition area 5 where theshield part 4 is pivoted in relation to thehandle part 3 by a pivoting action on thepivoting handle 17 by one hand while holding thehandle part 3 with the other hand. - From
FIG. 3 andFIG. 4 which are rear and front end views, respectively, the locking elements on the shield part and the handle part appear more clearly. Upon pivoting of the shield part in relation to the handle part these locking elements are caused to interact. -
FIG. 5 andFIG. 6 , which are bottom and top views, respectively, illustrate the locking elements in further detail. - From
FIG. 7 thefastening site 14 for the rigid needle in the hub becomes apparent. The rigid needle is preferably secured in the correct position by a press fit connection or by gluing or welding. - From
FIG. 8 andFIG. 9 it appears that thebarbs flanges transition area 5 together with the bend needle provide a biasing effect between theflanges barbs half tube 6 ensuring that unintended contact with the needle is avoided. This becomes especially clear inFIG. 9 where a part of the hub is cut away. - From
FIG. 10 andFIG. 11 a field of use for the puncturing device appears. The puncturing device is inserted into aninfusion device 18 for subcutaneous delivery of medication to a patient. This infusion device comprises a housing 19 in which acavity 20 is provided and where abore 21 leads medication from a pump or the like via aconnector 25 to thecavity 20 where asoft cannula 22 is provided in fluid contact with thecavity 20 and where afurther bore 23 covered with a self-sealingseptum 24 is provided opposite thesoft cannula 22. The puncturing device is inserted through the self-sealingseptum 24, thecavity 20 and thesoft cannula 22 and extends beyond the outer tip of the soft cannula. The puncturing device is held in place in relation to theconnector 25 by means ofbarbs handle part 3 againts the pivotinghandle 17 the barbs will release from their gripping position on the downward facing side of theconnector 25 and the puncturing device may be retracted from the infusion set. The soft cannula is placed in an operational position, i.e. in a subcutaneous infusion site, by penetrating the skin and tissue of the patient by means of the puncturing device and afterwards retracting the puncturing device through the soft cannula, the cavity and the self-sealing septum. The puncturing device is not intended for further use and should therefore be folded and brought into a locked position as shown inFIG. 8 andFIG. 9 prior to discarding hereby ensuring that unintended harmful injuries caused by an exposed needle are avoided.
